GASOLENE SO'LDERlNG-IRON.

SPECIFICATION formingpart of Letters Patent No. 740,112, dated September 29, 1903.

Appiicationtiedliprns,190s. saranno. 151,008. (Nomade.)

the handle of the iron and gas may be gen-A erated,so as to keep the iron at a uniform heat.

With these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated bythe claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specication, in which- Figure 1 represents a side elevation of our improved iron; Fig. 2, alongitudinal section through the forwardend of the iron; Fig. 3, a longitudinal section through the rear portion of the iron, the cover` not being shown;

Fig. 4, an end View of the plug inwhich the valve-stem is threaded.

Y A represents a cylinder adapted to contain the gasolene, and brazed upon the for- Ward end of this cylinder is an attachment B, which is reduced at its forward end, so as to form the neck B'. Upon the forward end of `this attachment B is formed a iiange or shoulder B2, andthisattachment is externally threaded forward of this shoulder and is also internally threaded, as represented at B3.

C is a plug which is threaded into the fori Ward end of the attachment B, and this plug is internally threadedv for the reception of the forward threaded end of the valve-stem D. The plug C is provided lwith anannular groove E, formed around its periphery near the rearward end thereof. F is a hole or passage extending from theinterior of the attachment Band communicates with this annular groove.

like. `coming in direct contact with the plug C.

Upon theopposite side of the plug is a passage G, which extends from the annular groove at an angle and communicates with the chamber forward of the threaded portion of the valve-stem.

H is a small plug threaded into the forward end of the plug C, and through the center of this plug H is formed a passage very small in diameter and countersunk at its rearward end for the reception of the conical end of the needle-valve'D. Back of the plug C, within the neck of the attachment B, we provide absorbent material I, such as wicking and the This prevents the free gasolene `from J represents the ironholder,`which is in the form ofa cylinder bent at right angles at its outer end, as represented at J, and

vthis cylinder is threaded upon the forward end of the attachment B against the shoulder B2, and near the rearward end ofthe cylinder .I are provided a series of slots K for the admission of air, and for the purpose of regulating the quantity of air passing through these slots we provide around the exterior of `the cylinder a sleeve L, which is provided lwith slots L', corresponding to the slots in :the cylinder, and by turning this cylinder the lslots L may be brought in or out ofregister `with the slots K, and thus regulate the inlet of air.

The soldering-iron M is inserted in the fright-.angle portion J of the iron-holder and may be heldin place by the set-screw N. To Ithe rearward end of the gasolene-cylinder A is brazed a cap O, which is provided at its rearward end with a stuffing-box and gland P, through which the valve-stem D extends. A knob D2 is secured at the outer end of the valve-stem D for the purpose of turning the same.

Q is a nipple extending through theside of the cap O for the purpose of filling the cylinder A with gasolene, and this nipple is ordinarily closed by a screw-cap R. S is a perforated cover surrounding the cylinder, so as to prevent the burning of the operators hands. In operation the attachment B is exposed to heat from the exterior for ashort time until gasis generated within the cylinder, and then by turning the needle-valve a slight distance the gas will pass through the passage F, around the annular groove E, through the passage G, through the opening H', and then mixing with the air coming through the slots K will burn with an intense heat through the iron-holder J, and thus heat the iron M, and this flame will sufficiently heat the gasolene contained in the wicking at the rear of the plug Cto keep on generating the gas in the well-known manuel'.

Of course we do not wish to be limited to the exact construction here shown, as slight modifications could be made without departing from the spirit of our invention.

Having thus fully described our invention, what we claim as new and useful isl. In a gasolene soldering-iron, a hollow handle adapted to contain the gasolene, a plug threaded in the forward end ofsaid handle, a valve-stem threaded through the plug, said valve-stem extending entirely through the handle and through the stung-box at the rear of the handle andprovided upon its rear endwith a knob, an annular groove provided in the plug around its periphery, a passage extending from the interior of the handle to the rear of the groove, a passage extending from the ann ular groove to the point forward of the thread ed portion of the valve-stem, a burnerplug threaded in the forward end of the other plug provided through its center with a small opening, said opening having a valve-seat for the needle-valve atits rear end, an iron-holder threaded on the forward end of the handle, means for removably securing the iron in the holder, means for admitting air to the interior 0f the iron-holder, and means for regulating the air-supply, as specified.

2. Ina gasolene soldering-iron of the character described, a handleadapted to contain the gasolene, a valve-stem extending longitudinally through the handle and protruding from the rearward end thereof through a suitable stuffingbox, a knob for turning the valve-stem located upon the rear end, a plug secured in the forward end of the handle, the forward end of the valve-stem threaded within this plug, an annulargroove formed around the plug near its rearward end, a passage extending from the interior of the handle to this annular groove, a passage located upon the opposite side of the plug extending from the annular groove to the chamber formed by the threaded portion of the plug forward of the threaded portion of the valve-stem, a burnerplug threaded in the forward end of the other plug, said burner -plug provided with an opening formed therethrough, a seat formed at the rear of the burner-plug for the needle-valve, an iron-holder threaded upon the forward end of the handle, said ironholder being cylindrical in form and bent at right angles at its outer end, a soldering-iron adapted to be secured in the outer right-angle portion, means for securing the iron in place, slots formed through the cylinder of the iron-holder near its rearward end, a sleeve surrounding the iron-holder and provided with slots corresponding to the slots through the iron-holder, said cylinder adapted to revolve around the holder for regulating the supply of air, as specified.

3. A gasolene soldering-iron, a cylinder adapted to contain the gasolene, an attachment secured to the forward end of the cylinder, said attachment being provided with a shoulder or flange near its forward end and being exteriorly threaded forward of the flange or shoulder, said attachment being interiorly threaded, a plug threaded into the forward end of the attachment, a needlevalve stem threaded through the plug, said plug being provided with an annular groove formed around its periphery near its rearward end, a passage extending from the interior of the attachment to the annular groove, a passage extending from the annular groove to a point forward of the threaded portion of the valve-stem, absorbent material located in the attachment at the rear of the plug, a burner-plug threaded in the forward end of the other plug, said burner-plug being provided with an opening formed therethrough, small in diameter, a valve-seat at the rear of the burner-plug, an iron-holder threaded over the forward end of the attachment, a soldering-iron, means for removably securing the soldering-iron in the outer end of the-ironholder, slots formed through the iron-holder near its rearward end, means for opening or closing these slots to regulate the supply of air, a cap secured to the rear of the gasolene-cylinder, a stungbox secured to the cap at the rear through which the valve-stem extends, a knob secured upon the rearward end of the valve-stem, an opening formed through the cap, a closure for said opening, and a perforated handle surrounding the cylinder, as specified.

In testimony whereof we have hereunto affixed our signatures in the presence of two subscribing witnesses.
